In a study of 124 dating couples, we tested a discrete systems model of the functions of two emotion systems in romantic relationships: love and anger/upset. This model posits that the operation of these systems reflects adaptations shaped by natural selection to solve different adaptive problems. Accordingly, we hypothesized that the love and anger/upset emotion systems would be largely indepe...

The occurrence of a multiple node upset is likely to increase significantly in nanoscale CMOS due to reduced device size and power supply voltage scaling. This paper presents a comprehensive treatment (model, analysis and design) for hardening a memory cell against a soft error resulting in a multiple node upset at 32nm feature size in CMOS. A novel 13T memory cell configuration is proposed, an...

This paper details the design and development of the Airborne Subscale Transport Aircraft Research (AirSTAR) test-bed at NASA Langley Research Center (LaRC). The aircraft is a 5.5% dynamically scaled, remotely piloted, twin-turbine, swept wing, Generic Transport Model (GTM) which will be used to provide an experimental flight test capability for research experiments pertaining to dynamics model...

Digital Signal Processors (DSP) embedded in FPGAs are irradiated with heavy ions in order to further understand the impact of particle-induced Single Event Effects (SEE) to their functionality. SEE upset duration and start-time measurements taken of various DSPs simultaneously during irradiation experiments provide a portrait of the various contributing upset mechanism as well as on-orbit rate ...

Associated with this gamma dot environment is dose rate upset threshold level. Knowledge of this threshold level enables system designers to determine the circumvention scheme that will prevent data loss. The upset threshold level varies with each Advanced CMOS process, layout (design rules), and device-circuit design. This is generally one to two orders of magnitude lower than the latchup level.
